Frame type hydrocylinder compressing bander density control room

Abstract

The invention relates to a frame-type hydraulic oil cylinder for compressing a density control room of a baler, and belongs to the technical field of balers. The invention includes an upper left fixed frame, an upper right fixed frame, a lower left fixed frame and a lower right fixed frame installed at the four corners of a rectangle, a movable frame is installed between the two adjacent fixed frames, and three-stage ring frames are installed in sequence in the longitudinal direction of the frames, Two vertical hydraulic oil cylinders are fixed at both ends of the upper connecting rod and the lower connecting rod, and a horizontal hydraulic oil cylinder is fixed at the lower ends of the left connecting rod and the right connecting rod. It moves vertically and horizontally to achieve vertical and horizontal compression of the straw. The fixed frame installed at the four corners ensures the uniform size of the straw. The frame is welded by channel steel and flat plate. There are gaps between the frames to ensure the strength while Filter out the dirt and other impurities mixed in the straw.

Description

technical field [0001] The invention relates to a frame-type hydraulic oil cylinder for pressing a density control room of a baler, belonging to the technical field of balers. Background technique [0002] The current density control room of the baler has the following three problems: First, the screw nut is used for compression. During the working process of the baler, the tractor driver needs to adjust the pressure according to the needs, and the adjustment process is operated by the driver. The pre-tightening operating lever in the cab is cumbersome to operate, which distracts the driver's attention, not only increases the driver's labor intensity, but also causes potential safety hazards; As a result, the compaction direction is single, and the density of the bale is low, which is not conducive to the transportation and storage of the bale. Third, the density control room of the baler adopts a plate structure, and impurities such as soil mixed in the straw are also mixed...

The pre-tightening operating lever in the cab is cumbersome to operate, which distracts the driver's attention, not only increases the driver's labor intensity, but also causes potential safety hazards; As a result, the compaction direction is single, and the density of the bale is low, which is not conducive to the transportation and storage of the bale. Third, the density control room of the baler adopts a plate structure, and impurities such as soil mixed in the straw are also mixed in during the compaction process. In the bale, resulting in high soil content in the bale
